Description

Technical Field

[0001] The invention belongs to the field of washing equipment, and in particular, relates to a micro-line dust collecting device, a control method and washing equipment. Background Art

[0002] Microlint is the fiber debris from clothing that falls off during the washing process due to friction between clothing and washing machines. Larger microlints are several millimeters long and enter the soil after being discharged into the water, causing soil compaction and affecting the growth of crops. Smaller microlints are only a few microns in size. In addition, due to the widespread popularity of chemical fiber clothing, the microlints produced during the washing process are also called microplastics, which can enter the human blood through the food chain.

[0003] Currently, researchers have found the above-mentioned micro-lint in the blood of embryos. Although the direct health effects of micro-lint on the human body are still unclear, for the long-term consideration of human health, some regions have implemented step-by-step management of micro-lint emissions, striving to cut off micro-lint emissions from the source. Therefore, washing equipment such as washing machines can only be improved to filter and collect the micro-lint generated during the washing process.

[0004] Existing devices for collecting micro-lint used in washing equipment often require users to manually clean the storage cavity for lint after filtering. And in general, the above-mentioned device filters out micro-lint together with larger coarse lint, causing the lint to accumulate quickly, requiring users to frequently clean it manually. However, in the current scheme, the filtered lint is often collected in a state of high humidity, and even during the filtering process, it is easy for some water to enter the above-mentioned cavity along with the lint, causing the collected lint to be in a humid environment for a long time, which is then prone to mold and produce odor, resulting in a poor experience for users when cleaning the lint.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a micro-lint collection device, a control method and a washing device, which can reduce or even prevent water from entering the chamber for storing micro-lint, improve the dryness of the micro-lint storage environment, prevent the micro-lint from mold and odor during storage, compress the volume of the micro-lint, and reduce the number of times users clean up, or even eliminate the need for users to clean up at all.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A micro-wire scraps collecting device, comprising:

[0009] The collecting unit comprises a collecting cylinder provided with a filtering part, and a rotating shaft extending along the axial direction of the collecting cylinder, wherein the rotating shaft is movably installed in the collecting cylinder along the axis thereof, and a spiral sheet is provided on the side wall of the rotating shaft;

[0010] A storage unit is arranged at the first end of the collecting cylinder, and an openable and closable sealing component is arranged between the collecting cylinder and the storage unit;

[0011] The puncture part is arranged at one end of the rotating shaft close to the sealing assembly, and is used to move along the axis with the rotating shaft to push open the sealing assembly to connect the collecting cylinder and the storage unit;

[0012] The spiral sheet is used to rotate with the rotating shaft to send the micro-wire scraps accumulated in the collecting cylinder into the storage unit.

[0013] Furthermore, the sealing assembly comprises a sealing valve sheet made of elastic material, the sealing valve sheet is sealingly installed at a position where the storage unit is connected to the collecting cylinder, and a cutout is arranged on the sealing valve sheet;

[0014] The puncture portion moves with the rotating shaft and passes through the sealing valve sheet via the incision. The sealing valve sheet forms a gap connecting the collecting cylinder and the storage unit at the position of the incision.

[0015] Furthermore, the micro-line scraps collecting device further comprises a compression member, which is arranged inside the collecting barrel near the first end of the collecting barrel and can move along the axis direction of the collecting barrel along with the rotating shaft;

[0016] The compression member has a funnel-shaped structure with a diameter gradually reduced toward the sealing assembly, and the puncture portion is formed at a small-diameter end of the funnel-shaped structure;

[0017] The funnel-shaped structure has a compression channel with a gradually decreasing inner diameter, which is used to receive micro-wire chips sent in by the rotation of the spiral blade through its large diameter end. After the micro-wire chips are compressed through the compression channel, they are discharged from the small diameter end of the compression channel into the storage unit.

[0018] In the above scheme, after the micro-wire scraps are compressed through the compression channel, their density is increased and their volume is reduced, and they are then sent to the storage unit for storage, which greatly reduces the space occupied by the micro-wire scraps and can reduce the number of times users need to clean them, or even eliminate the need for users to clean them.

[0019] Furthermore, an end cap having a threaded hole in the middle is provided at the second end of the collecting cylinder, and a shaft head is provided at one end of the rotating shaft away from the sealing assembly, and the shaft head is installed in the threaded hole;

[0020] The shaft head has a threaded section in the middle along the axial direction, and the threaded section is threadedly connected with the threaded hole; both sides of the threaded section of the shaft head are optical shaft sections without threaded structures, and the diameter of the optical shaft section is smaller than the diameter surrounded by the top of the internal thread in the threaded hole;

[0021] Preferably, the micro-wire chip collection device also includes a transmission shaft for driving the rotating shaft to rotate around its own axis; a connecting hole is provided on the shaft head, and one end of the transmission shaft is slidably inserted in the connecting hole along the axial direction and cooperates with the connecting hole in the circumferential upper limit position.

[0022] Furthermore, the filter part is arranged on the side wall and bottom wall of the collecting tube, and is spaced apart from both ends of the collecting tube;

[0023] The arrangement range of the spiral sheet along the axis of the rotating shaft at least extends from the area between the filter portion and the first end of the collecting cylinder to the area between the filter portion and the second end of the collecting cylinder;

[0024] Preferably, a water collecting tank is provided below the filter portion for receiving the filtered water discharged from the water outlet.

[0025] Furthermore, the micro-wire cuttings collection device also includes a first heating unit, which is arranged on the outside of the collection tube, close to the first end of the collection tube; and / or the micro-wire cuttings collection device also includes a second heating unit, which is arranged on the outside of the collection tube, close to the second end of the collection tube.

[0026] Furthermore, a water inlet is arranged on the side wall of the collecting cylinder, and the water inlet is arranged in the upper area of ​​the side wall of the collecting cylinder, and the downward projection of the water inlet is staggered with the rotating shaft.

[0027] Furthermore, the axis of the collecting tube is inclined relative to the horizontal direction, and the first end of the collecting tube is higher than the second end of the collecting tube.

[0028] A control method for the micro-wire scraps collecting device described above comprises:

[0029] The rotating shaft is driven to rotate in the first direction and approach the sealing assembly along the axis, driving the puncture portion to move and push open the sealing assembly; the rotating shaft continues to rotate in the first direction, and the spiral sheet rotates with the rotating shaft, so that the micro-wire scraps accumulated in the collection barrel are sent into the storage unit through the pushed-open sealing assembly;

[0030] Furthermore, the rotating shaft is driven to rotate in a second direction opposite to the first direction and away from the sealing assembly along the axis, and the puncture portion is separated from the sealing assembly under the action of an elastic member, and the sealing assembly remains in a sealed state; the spiral sheet rotates with the rotating shaft to transport the micro-wire scraps accumulated in the collection barrel in a direction away from the sealing assembly and squeeze and dehydrate them.

[0031] A washing device comprises the micro-line scraps collecting device described above.

[0032] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0033] In the present invention, a sealing assembly is provided between the collecting tube and the storage unit in the micro-thread scraps collecting device. Only when the micro-thread scraps need to be fed into the storage unit, the sealing assembly is pushed open by the puncture portion, thereby connecting the collecting tube and the storage unit. In this way, when the thread scraps do not need to be fed in, water or moisture in the collecting tube can be prevented from entering the storage unit, thereby improving the dryness of the micro-thread scraps stored in the storage unit and avoiding the problem of the micro-thread scraps being too wet and moldy.

[0034] In the present invention, the micro-thread scraps accumulated in the collection tube are sent to the storage unit through the compression channel in the compression member, which can compress the micro-thread scraps and greatly reduce the volume of the micro-thread scraps, thereby helping to increase the amount of micro-thread scraps that can be stored in the storage unit. In addition, during the compression process, the moisture carried by the micro-thread scraps can be further squeezed out, further improving the dryness in the storage unit.

[0035] In the present invention, the water outlet of the collection barrel is spaced from both ends of the collection barrel, and the collected micro-thread scraps are mainly concentrated in the middle area of ​​the collection barrel. By controlling the rotation direction of the rotating shaft, the micro-thread scraps can be transported to the end where the storage unit is located for storage, or transported to the end away from the storage unit and squeezed to reduce the water content of the micro-thread scraps before being sent to the storage unit. Through the provision of the first heating unit and / or the second heating unit, the micro-thread scraps accumulated in the collection barrel can also be dried first, and then sent to the storage unit after drying, thereby ensuring the dryness of the micro-thread scraps in the storage unit to the greatest extent.

[0048] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0050] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] like Figure 1 As shown, the embodiment of the present invention provides a micro-lint collecting device 500 and a control method thereof, and a washing device having the micro-lint collecting device 500. The washing device may be a washing machine, a washer-dryer, a care machine, or other washing device having a clothes washing function.

[0053] Specifically, the washing device includes a housing 100, a water drum 200 is connected to the housing 100 through a hanging device (not shown in the figure), and a washing drum is also arranged in the water drum 200 for holding the laundry. A door 300 is hingedly connected to the front side of the housing 100 for blocking the laundry openings of the washing drum and the water drum 200.

[0054] The drainage system of the washing device has a filtering function, and can filter the washing water in the water holding drum 200 before discharging it, thereby preventing the micro-thread scraps in the washing water from being directly discharged with the drainage water flow.

[0055] The drainage system at least includes a lint separation device 490 connected to the water drum 200, and the lint separation device 490 is provided with a water inlet 4921 and a clean water outlet 4922. The water in the water drum 200 enters the lint separation device 490 through the water inlet 4921, and is discharged from the clean water outlet 4922 after being filtered. The clean water outlet 4922 is connected to a clean water outlet pipe 460, and the clean water outlet pipe 460 is further connected to an external drainage pipe 461. The external drainage pipe 461 extends to the outside of the housing 100, and is used to drain water to the outside of the washing device. For example, the end of the external drainage pipe 461 can be inserted into the floor drain of the user's home.

[0056] Through the above structure, when the washing water in the water holding drum 200 is discharged, it is first filtered by the lint separation device 490, and the micro lint in the water is intercepted, and the filtered clean water is discharged into the clean water outlet pipe 460, and then discharged from the washing device along the external drain pipe 461. In this way, the purpose of preventing the discharge of micro lint can be achieved.

[0057] Furthermore, a water pump 420 is provided at the bottom of the housing 100, and the bottom of the water drum 200 is connected to a water diversion pipe 410, which is connected to the water inlet end of the water pump 420 through the water diversion pipe 410. The water outlet end of the water pump 420 is connected to one end of the water delivery pipe 450, and the other end of the water delivery pipe 450 is connected to the water inlet 4921 of the lint separation device 490, so that the washing water in the water drum 200 can be driven by the water pump 420 to enter the lint separation device 490 for filtration.

[0058] Furthermore, the wire scrap separation device 490 includes a cylindrical housing 492, a driving motor 491 fixed to the outside of the housing 492, and a cylindrical filter 493 connected to the output shaft of the driving motor 491 and rotatably mounted inside the housing 492. The two ends of the filter 493 abut against the two end faces of the housing 492, and both maintain a rotatable sealed connection with the housing 492. In this way, the housing 492 and the filter 493 form two spaces, and the water inlet 4921 is arranged on the housing 492, and communicates with the space surrounded by the housing 492 and the outside of the filter 493. The water filtered by the filter 493 enters the cylindrical space inside the filter 493, and the end of the housing 492 where the driving motor 491 is not installed is provided with a circular opening at the center of the circle as a clean water outlet 4922, and the diameter of the clean water outlet 4922 is less than or equal to the diameter of the filter 493, and the filtered water can flow out from the clean water outlet 4922.

[0059] It is understandable that the filtering accuracy of the filter 493 needs to be sufficient to intercept the micro-wires carried in the water flow and the emission level prohibited by regulations.

[0060] Furthermore, the clean water outlet pipe 460 is connected to a three-way valve 470, and is respectively connected to the external drainage pipe 461 and the internal circulation pipe 462 through the three-way valve 470. The three-way valve 470 is a two-position three-way solenoid valve, which can control the external drainage pipe 461 and the internal circulation pipe 462 to be connected to the clean water outlet pipe 460. The internal circulation pipe 462 is connected to the top of the water storage cylinder 200 and is connected, or is connected to the observation window pad at the mouth of the water storage cylinder for circulation filtration during washing. That is, by controlling the conduction direction of the clean water outlet pipe 460 through the three-way valve 470, the same wire scrap separation device 490 can be used to achieve two filtering functions: circulation filtration of washing water and drainage filtration.

[0061] When the washing device is working, during the washing and rinsing process, the three-way valve 470 conducts the clean water outlet pipe 460 and the inner circulation pipe 462, and the water pump 420 operates intermittently or continuously to pump the washing water in the water drum 200 to the lint separation device 490 and enter the space between the housing 492 and the filter 493. After the lint and other impurities in the washing water are filtered by the filter 493, they enter the space inside the filter 493, flow from the clean water outlet 4922 to the clean water outlet pipe 460, and guide the water along the inner circulation pipe 462 to flow into the water drum 200 again. At the same time, the driving motor 491 is started, driving the filter 493 to rotate, and the lint blocked by the filter 493 and adhering to the filter 493 is thrown to the edge of the housing 492 under the action of centrifugal force, so that the filter 493 remains unobstructed.

[0062] After washing and rinsing, the washing equipment performs a drainage operation and controls the three-way valve 470 to switch the conduction direction, that is, to connect the clean water outlet pipe 460 and the external drain pipe 461. Then the water pump 420 starts to run and pumps the washing water in the water drum 200 to the wire chip separation device 490 for filtration. The filtered clean water flows from the clean water outlet pipe 460 to the external drain pipe 461, and is finally discharged to the outside of the washing equipment along the external drain pipe 461.

[0063] In the above manner, the washing machine can circulate and filter to remove lint in the washing water during the washing process, thereby improving the washing effect of clothes. The drainage water flow of the washing machine first passes through the lint separation device 490 before being discharged, which can intercept micro-lint in the drainage water flow, thereby solving the problem of excessive micro-lint content in the drainage water flow.

[0064] In a further solution, the wire scrap separation device 490 also has a wastewater outlet 4923 , through which the filtered wire scraps and other impurities can be discharged along with the water flow, thereby achieving self-cleaning of the wire scrap separation device 490 .

[0065] Specifically, the wastewater outlet 4923 is arranged at the bottom of the housing 492, and is connected to the space enclosed by the housing 492 and the outer side of the filter screen 493. The wastewater outlet 4923 is connected to the wastewater return pipe 440, and a control valve 480 for controlling the on-off of the wastewater return pipe 440 is arranged on the wastewater return pipe 440, and the control valve 480 can be a two-way solenoid valve. The end of the wastewater return pipe 440 is connected to a micro-wire scrap collecting device 500, which can receive the wastewater mixed with high-concentration wire scraps discharged by the wire scrap separation device 490, and collect the wire scraps, including micro-wire scraps, therein.

[0066] More specifically, the axis of the shell 492 of the wire scrap separation device 490 extends in a horizontal or nearly horizontal direction, the water inlet 4921 is arranged near the top of the shell 492, and the waste water outlet 4923 is arranged near the bottom of the shell 492. In this way, the washing water entering the shell 492 flows downward under the force of gravity, and can more fully contact the filter 493 to achieve filtration, and the inflowing water can also play a certain flushing effect on the filter 493. The filtered wire scraps and the undischarged water are collected at the bottom of the shell 492, and can be discharged more thoroughly from the wire scrap separation device 490.

[0067] As a specific implementation, the water inlet 4921, the clean water outlet 4922 and the waste water outlet 4923 are all arranged on the end wall of the housing 492 at the end where the drive motor 491 is not installed. However, it can be understood that the water inlet 4921 and the waste water outlet 4923 can also be arranged at other positions, as long as the wire scraps in the housing 492 can be fully discharged with the water flow through the waste water outlet 4923.

[0068] In this embodiment, the micro-lint collecting device 500 is disposed at a height lower than the wastewater outlet 4923, and the wastewater return pipe 440 at least partially extends downward, so that the wastewater can be discharged to the micro-lint collecting device 500 by gravity.

[0069] Specifically, the micro-lint collecting device 500 is disposed in the bottom area of ​​the housing 100. When the control valve 480 is opened to allow the wastewater return pipe 440 to be connected, wastewater mixed with high-concentration lint can flow toward the micro-lint collecting device 500 autonomously under the action of gravity.

[0070] Furthermore, the micro-thread collecting device 500 has the ability to filter wastewater and can intercept micro-threads in the wastewater. After the wastewater entering the micro-thread collecting device 500 is filtered, the impurities containing micro-threads carried therein can be separated from the water, and the water without micro-threads can be discharged through the inner drain pipe 564 connected to the bottom of the micro-thread collecting device 500.

[0071] In detail, the filtration accuracy that can be achieved by the micro-thread collecting device 500 is at least not lower than the filtration accuracy of the filter screen 493 in the thread separation device 490. In this way, it can be ensured that the impurities such as thread scraps carried in the wastewater discharged by the thread separation device 490 can be completely collected in the micro-thread collecting device 500.

[0072] In the washing equipment having the above structure, the control valve 480 is kept closed during the washing, rinsing and draining process. After dehydration, the water pump 420 is in a closed state, and at this time, the amount of water in the housing 492 of the lint separation device 490 is very small, but mixed with lint. After opening the control valve 480, under the action of gravity, the wastewater mixed with lint will flow into the micro-lint collection device 500 through the wastewater return pipe 440, and after being filtered by the micro-lint collection device 500, the micro-lint is separated from the wastewater.

[0073] However, since the micro-thread chips are mixed with wastewater and enter the micro-thread chip collection device 500, if the filtered micro-thread chips are directly collected in the micro-thread chip collection device 500, the micro-thread chips contain more water, which will cause the space for storing micro-thread chips inside the micro-thread chip collection device 500 to be in a humid environment for a long time. Furthermore, at room temperature, micro-thread chips that have been stored for a long time are prone to mold and produce odor. Existing micro-thread chip collection devices 500 generally require users to manually clean the micro-thread chips stored therein on a regular basis, and the odor of moldy micro-thread chips will seriously affect the user's experience during the cleaning process. In addition, since the existing micro-thread chip collection is collected together with the coarse thread chips, the amount of micro-thread chips generated is large and the volume is also large. Usually, they need to be cleaned every dozens of cycles, which is very inconvenient for users.

[0074] Embodiment 1

[0075] This embodiment is used to solve the problem that the storage environment of micro-lint in the washing machine is too humid, prone to mold and produce odor.

[0076] Specifically, Figures 1 to 7 As shown, this embodiment provides a micro-thread scraps collection device 500 used in the above-mentioned washing equipment, including a collection unit 530 and a storage unit 510. The collection unit 530 is connected to the wastewater return pipe 440 in the washing equipment, and is used to receive wastewater carrying micro-thread scraps and collect micro-thread scraps from the wastewater. The storage unit 510 is connected to the collection unit 530, and the micro-thread scraps accumulated in the collection unit 530 are finally sent to the storage unit 510 for storage.

[0077] More specifically, in this embodiment, the collection unit 530 includes a collection barrel 538 provided with a filter 539, and a rotating shaft 532 extending along the axial direction of the collection barrel 538. The rotating shaft 532 is movably installed in the collection barrel 538 along its axis, and a spiral sheet 531 is provided on the side wall of the rotating shaft 532. The storage unit 510 is provided at the first end (i.e., Figure 2 and Figure 3 An openable and closable sealing assembly is provided between the collecting cylinder 538 and the storage unit 510.

[0078] A puncture portion 5221 is provided at one end of the rotating shaft 532 close to the sealing assembly. When the rotating shaft 532 moves along its axis, the puncture portion 5221 can be driven to move synchronously. When the puncture portion 5221 moves to the left along with the rotating shaft 532, the sealing assembly can be pushed open, thereby connecting the collecting barrel 538 and the storage unit 510. The spiral piece 531 provided on the side wall of the rotating shaft 532 can rotate synchronously with the rotating shaft 532, thereby sending the micro-wire scraps accumulated in the collecting barrel 538 into the storage unit 510 along its spiraling direction.

[0079] In this embodiment, wastewater carrying micro-wire scraps enters the collection tube 538 of the micro-wire scraps collection device 500, and the filter 539 on the collection tube 538 filters the wastewater, and collects the micro-wire scraps and other impurities inside the collection tube 538. The outer diameter of the spiral piece 531 is substantially consistent with the inner diameter of the collection tube 538, and the two are matched with a small gap. The spiral piece 531 is driven to rotate synchronously by driving the rotating shaft 532 to rotate in the first direction, and the spiral piece 531 can be used to scrape off the micro-wire scraps attached to the inner wall of the collection tube 538, and push the micro-wire scraps to the left end of the collection tube 538.

[0080] During the process of rotating shaft 532 rotating in the first direction, it also moves leftward along its axis, driving the puncture portion 5221 at its left end to move leftward synchronously, so as to push open the sealing assembly between the collection barrel 538 and the storage unit 510. In this way, the collection barrel 538 and the storage unit 510 are connected, and the micro-wire scraps in the collection barrel 538 can be sent to the storage unit 510 for storage. When it is not necessary to send micro-wire scraps to the storage unit 510, the puncture portion 5221 does not act on the sealing assembly, so that it remains in a blocked state, and then the storage unit 510 and the collection barrel 538 are completely separated, so that water or moisture in the collection barrel 538 can be prevented from entering the storage unit 510.

[0081] Through the above scheme, when there is no need to feed micro-wire scraps into the storage unit 510, the storage unit 510 as a whole is a sealed structure, which significantly improves the dryness of the internal environment of the storage unit 510 and effectively prevents problems such as mold and odor caused by long-term storage of micro-wire scraps in a humid environment.

[0082] As a preferred implementation of this embodiment, the storage unit 510 includes a storage cylinder 511 made of hard material and a flexible connecting portion 512. The internal cavity of the storage cylinder 511 is used to store micro-thread scraps, and the right end of the connecting portion 512 is connected to a hard section, which is connected to the left end of the collecting cylinder 538 through the hard section. Due to the flexible nature of the connecting portion 512, it can be deformed, and then the angle of the storage cylinder 511 can be appropriately adjusted to make it high at the right end and low at the left end, so as to prevent the micro-thread scraps from accumulating at the entrance of the storage unit 510.

[0083] More preferably, a desiccant is placed in the storage cylinder 511 in advance, and the desiccant can absorb the water vapor that enters when the sealing component is briefly opened when the micro-wire scraps are fed in, thereby further ensuring the dry state inside the storage unit 510.

[0084] Further, in this embodiment, the sealing assembly includes a sealing valve sheet 513 made of elastic material, the sealing valve sheet 513 is sealingly mounted on the storage unit 510 at the opening for connecting the collection cylinder 538, or mounted on the collection cylinder 538 at the opening for connecting the storage unit 510, and a cutout is provided on the sealing valve sheet 513. The puncture portion 5221 moves leftward along with the rotating shaft 532, passes through the sealing valve sheet 513 through the cutout, and the sealing valve sheet 513 forms a gap connecting the collection cylinder 538 and the storage unit 510 at the position of the cutout.

[0085] More specifically, the sealing valve plate 513 is installed in the storage unit 510, specifically in the hard section at the right end of the connecting portion 512, and the outer periphery of the sealing valve plate 513 is sealed and connected to the inner wall of the hard section. Figure 6 and Figure 7 The incisions on the sealing valve plate 513 include a vertical incision 5131 and a horizontal incision 5132 that are vertically arranged.

[0086] The sealing valve disc 513 is a round cake structure made of flexible rubber or silicone, and a longitudinal cut 5131 and a transverse cut 5132 are arranged in the middle area to form a cross-shaped cut structure. In the absence of external force, the cross-shaped cut remains in close contact and is airtight, thereby ensuring the sealing state inside the storage tube 511. When the puncture portion 5221 is pressed from the right side, it can be opened from the position of the cross-shaped cut, so that micro-thread scraps can be fed into the storage tube 511. At the same time, the sealing valve disc 513 can fit more closely on the surface of the puncture portion 5221, reducing the moisture entering the storage tube 511 from between the sealing valve disc 513 and the puncture portion 5221. When the puncture portion 5221 moves to the right and withdraws, the cross-shaped cut is automatically closed, and the storage tube 511 returns to a sealed state.

[0087] In a further solution of this embodiment, the puncture portion 5221 is an internal hollow structure, and the micro-wire scraps accumulated in the collection tube 538 can be pushed into the interior of the puncture portion 5221 by the spiral blade 531, and finally discharged from the left end of the puncture portion 5221 passing through the sealing valve plate 513 and entering the storage tube 511.

[0088] Specifically, the micro-line dust collecting device 500 of this embodiment further includes a compression member 522 disposed inside the collecting barrel 538 near the left end, and the compression member 522 can move along the axis of the collecting barrel 538 along with the rotating shaft 532. The compression member 522 has a funnel-shaped structure with a diameter gradually decreasing from right to left, and a puncture portion 5221 is formed at the small diameter end of the funnel-shaped structure.

[0089] Both ends of the funnel-shaped structure are open, and there is a compression channel with a gradually decreasing inner diameter from right to left. The spiral blade 531 rotates to send the micro-thread scraps from the large diameter end (i.e., the right end in the figure) of the funnel-shaped structure into the compression channel. After the micro-thread scraps are compressed through the compression channel, they are discharged from the small diameter end of the compression channel into the storage cylinder 511 of the storage unit 510.

[0090] More specifically, the compression member 522 includes a guide portion 5223, a compression neck 5222 and a puncture portion 5221 which are connected in sequence from right to left. The compression neck 5222 and the puncture portion 5221 form the funnel-shaped structure. When the micro-thread scraps pass through the compression neck 5222, they are compressed, gradually become thinner, and have a higher density, so as to reduce the volume and facilitate passing through the sealing valve plate 513. The compression neck 5222 can be as follows: Figure 5 The arc transition structure shown in , may also be a standard frustum.

[0091] The guide portion 5223 is cylindrical and extends rightward from the right end of the compression neck 5222. The outer diameter of the guide portion 5223 is clearance-matched with the inner diameter of the collecting tube 538. When the compression member 522 moves along the axis with the rotating shaft 532, the guide portion 5223 cooperates with the side wall of the collecting tube 538 to ensure that the tip of the left end of the puncture portion 5221 is always located on the axis of the collecting tube 538, that is, always facing the intersection of the longitudinal incision 5131 and the transverse incision 5132 on the sealing valve plate 513.

[0092] Preferably, the outer periphery of the guide portion 5223 may be covered with a layer of material such as nylon to achieve lubrication and sealing with the inner wall of the collection tube 538. In this way, no water will accumulate on the outer periphery of the compression neck 5222 and the puncture portion 5221, further preventing the water in the collection tube 538 from entering the storage unit 510.

[0093] In this embodiment, when the rotating shaft 532 moves to the left and drives the compression member 522 to move to the left synchronously, the left end of the puncture portion 5221 first presses against the cross-shaped cutout of the sealing valve plate 513, and the rotating shaft 532 continues to push the compression member 522 to the left, and the puncture portion 5221 penetrates the sealing valve plate 513 and extends into the storage unit 510. At this time, the micro-thread scraps sent into the compression member 522 as the spiral plate 531 rotates are compressed, squeezed out of the puncture portion 5221 and enter the storage unit 510, and then the volume becomes slightly larger and after accumulating to a certain length, they are broken at the open end of the puncture portion 5221, and finally enter the storage unit 510 in a state of sections.

[0094] In the above manner, the micro-thread scraps do not contact the sealing valve plate 513 at all when entering the storage unit 510 , and the problem of the micro-thread scraps remaining at the cross-shaped cutout on the sealing valve plate 513 and affecting the sealing performance of the sealing valve plate 513 is avoided.

[0095] Furthermore, in order to send all the micro-wire scraps accumulated in the collection barrel 538 to the storage unit 510 as much as possible through the spiral blade 531, the outer diameter of the spiral blade 531 is substantially the same as the inner diameter of the collection barrel 538, so that the two are matched with a small gap. In this way, the micro-wire scraps attached to the inner wall of the collection barrel 538 can be fully scraped off by the spiral blade 531 without affecting the rotation of the spiral blade 531.

[0096] The spiral piece 531 needs to extend into the compression member 522 in order to deliver the micro-wire scraps into the compression channel inside the compression member 522 for compression. To this end, the diameter of the leftmost section of the spiral piece 531 is smaller than the other diameters. Specifically, the outer diameter of the leftmost section of the spiral piece 531 is consistent with the inner diameter of the guide portion 5223, and the two are matched with a small gap. When the rotating shaft 532 moves to the left, the left end of the spiral piece 531 abuts against the inner wall of the compression neck 5222, thereby pushing the compression member 522 to move to the left as a whole, so that the puncture portion 5221 opens the sealing valve piece 513.

[0097] Furthermore, an elastic member is provided in the collecting tube 538 for applying elastic force to the compression member 522, so that when the rotating shaft 532 moves to the right, the compression member 522 is reset to the right under the action of the elastic force, so that the puncture portion 5221 is withdrawn from the cross-shaped incision, and the sealing valve plate 513 resumes sealing.

[0098] Specifically, the elastic member is a compression spring 523 sleeved on the compression member 522, and an annular support sheet 521 is provided on the right side of the sealing valve sheet 513. The left end of the compression spring 523 abuts against the support sheet 521, and the right end abuts against the large diameter of the compression neck 5222. The rotation shaft 532 moves to the left to push the compression member 522 to move left, compressing the compression spring 523 on the left side. When the rotation shaft 532 moves to the right, the elastic force of the compression spring 523 pushes the compression member 522 to return to the right.

[0099] In this embodiment, the micro-line scraps are compressed and then sent to the storage unit 510 for storage. On the one hand, the moisture carried by the micro-line scraps can be further squeezed out during the compression process to improve the dryness of the micro-line scraps. On the other hand, the space occupied by the micro-line scraps is reduced, which can increase the amount of micro-line scraps that can be stored in the storage unit 510. By reasonably designing the volume of the storage cylinder 511, the storage cylinder 511 can be sufficient to store the collected micro-line scraps, so that the user does not need to clean it during the life cycle of the washing device, and the user experience is better.

[0100] In this embodiment, the rotating shaft 532 can rotate around its own axis and move along the axis, and when the rotating shaft 532 moves to the left to the extreme position, it can continue to rotate so as to continuously send the micro-thread scraps into the storage unit 510. To this end, the micro-thread scraps collecting device 500 of this embodiment further includes the following structure.

[0101] The second end of the collecting tube 538 (i.e. Figure 2 and Figure 3 An end cap 536 having a threaded hole in the middle is provided at the right end of the rotating shaft 532, and a shaft head 537 is provided at the right end of the rotating shaft 532, and the shaft head 537 is installed in the threaded hole. The shaft head 537 has a threaded section 5371 in the middle along the axial direction, and the threaded section 5371 is threadedly connected with the threaded hole. Both sides of the threaded section 5371 of the shaft head 537 are optical shaft sections without threaded structures, and the diameter of the optical shaft section is smaller than the diameter surrounded by the top of the internal thread in the threaded hole.

[0102] With the above structure, by driving the rotating shaft 532 to rotate, the threaded section 5371 on the shaft head 537 can cooperate with the threaded hole on the end cover 536, so that the rotating shaft 532 can generate movement along the axial direction while rotating. Specifically, the rotation direction of the spiral structure on the threaded section 5371 and the rotation direction of the spiral piece 531 on the rotating shaft 532 are set so that when the rotating shaft 532 rotates in the first direction, the shaft head 537 can drive the rotating shaft 532 to move leftward, and at the same time, the spiral piece 531 rotates to the left to transport the micro-wire scraps in the collecting cylinder 538.

[0103] The optical axis sections arranged on both sides of the threaded section 5371 ensure that the rotating shaft 532 can remain stationary in the axial direction after moving a certain distance in the axial direction, but the rotation of the rotating shaft 532 is not affected.

[0104] Specifically, when the wastewater carrying micro-filaments enters the collection cylinder 538, the micro-filaments collection device 500 is in Figure 2 In the collecting and filtering state shown, the rotating shaft 532 is located closer to the right side, the puncture portion 5221 and the sealing valve plate 513 are spaced apart, and the storage unit 510 remains sealed.

[0105] When the micro-thread scraps need to be sent to the storage unit 510, the drive shaft 532 rotates in the first direction. Figure 3 , the threaded section 5371 will be screwed into the threaded hole of the end cover 536. Since the end cover 536 is fixed, the shaft 532 will be driven by the shaft head 537 to move leftward, and push the compression member 522 to squeeze the compression spring 523, so that the puncture portion 5221 penetrates the sealing valve plate 513. When the threaded section 5371 is completely screwed out of the threaded hole, the shaft 532 is driven to rotate, and the shaft 532 will no longer move leftward. The micro-thread scraps accumulated in the collection tube 538 will be continuously pushed leftward and sent into the compression member 522 as the spiral sheet 531 rotates, and then compressed into a compact solid, and then cut off from the opening of the puncture portion 5221 and enter the storage unit 510.

[0106] After the micro-wire scraps are compressed and transported, the drive shaft 532 rotates in a second direction opposite to the first direction. Since the compression spring 523 always acts on the compression member 522 and transmits force to the shaft 532, the threaded section 5371 can quickly cut into the threaded hole in the middle of the end cover 536, and then the shaft head 537 and the shaft 532 rotate synchronously in the second direction, and the shaft 532 can be driven by the shaft head 537 to move rightward and reset. At the same time, the compression spring 523 pushes the compression member 522 to reset rightward, so that the puncture portion 5221 is withdrawn from the cross-shaped incision of the sealing valve plate 513, and the sealing valve plate 513 restores the sealing state of the storage unit 510.

[0107] In this embodiment, after a certain amount of micro-wire scraps are accumulated inside the collecting barrel 538, the rotating shaft 532 can also be driven to rotate in the second direction. After a period of time, since the optical axis section on the left side of the threaded section 5371 is in the threaded hole of the end cover 536, the rotating shaft 532 only rotates and no longer produces axial movement. In this process, the spiral piece 531 rotates in the second direction synchronously, which can push the micro-wire scraps in the collecting barrel 538 to gradually gather to the right end of the collecting barrel 538, and play a role in squeezing and dehydrating the micro-wire scraps. Then, the rotating shaft 532 is driven to rotate in the first direction, and the threaded section 5371 is screwed into the threaded hole on the end cover 536 until it is completely screwed out, so that the shaft head 537 drives the rotating shaft 532 to move a distance to the left and keep rotating. At this time, the puncture part 5221 pushes open the sealing valve plate 513, and the spiral piece 531 rotates continuously to transport the micro-wire scraps to the left end of the collecting barrel 538, and finally sends the micro-wire scraps into the storage unit 510.

[0108] In the above scheme, the shaft head 537 has a structure with a threaded section 5371 in the middle and smooth axis sections at both ends, which not only achieves the purpose of driving the rotating shaft 532 to move left and right, but also avoids self-locking and difficulty in rotation when the rotating shaft 532 moves to the left and right extreme positions.

[0109] Furthermore, the micro-line dust collecting device 500 described in this embodiment also includes a transmission shaft 572, which drives the rotating shaft 532 to rotate around its own axis through the transmission effect of the transmission shaft 572. Specifically, a connecting hole 5372 is provided on the shaft head 537, and the left end of the transmission shaft 572 is slidably inserted into the connecting hole 5372 along the axial direction, and cooperates with the connecting hole 5372 in the circumferential upper limit.

[0110] More specifically, the shaft head 537 is provided with a mounting hole with an opening on the right end face, a spline sleeve is provided in the mounting hole, and the spline sleeve forms the connecting hole 5372. The transmission shaft 572 has a spline structure matching the spline sleeve at least within a certain length range at the left end, so that it can cooperate with the spline sleeve and move left and right without affecting the torque transmission.

[0111] As a specific implementation of this embodiment, a worm gear transmission structure is used to drive the rotating shaft 532 to rotate. Specifically, the micro-line scraps collection device 500 also includes a collection motor 581, and the collection motor 581 has an output shaft 582, and a coaxially arranged worm 583 is connected to the end of the output shaft 582. A worm wheel 571 is arranged on the upper side of the worm 583 to cooperate with the transmission, and the transmission shaft 572 is coaxially fixed with the worm wheel 571 and rotates synchronously with the worm wheel 571.

[0112] More specifically, the transmission shaft 572 passes through the worm gear 571 , the left end of the transmission shaft 572 is inserted into the connecting hole 5372 of the shaft head 537 , and the right end is rotatably fixed on a support 573 .

[0113] In the above scheme, the worm gear 571 can be self-locking, the transmission ratio is large, and the transmission shaft 572 is not colinear with the output shaft 582 of the collection motor 581. In this way, when compressing the micro-wire scraps, the reaction force of the squeeze will not be transmitted to the output shaft 582 of the collection motor 581, and the structure is more reliable.

[0114] It is understandable that a rotary gear transmission may also be used, or a high-torque motor may be used to directly drive the shaft to rotate.

[0115] In this embodiment, since a threaded hole is provided on the end cover 536 at the right end of the collecting tube 538, that is, it has an open structure, in order to prevent water from leaking from the right end of the collecting tube 538, the following structure is further provided for sealing.

[0116] Specifically, a shoulder 533 extending toward the outer circumference is provided on the side wall of the rotating shaft 532 in the area near the shaft head 537. A sealing gasket 534 and a gasket 535 are mounted on the rotating shaft 532 between the shoulder 533 and the shaft head 537, and the sealing gasket 534 is clamped between the shoulder 533 and the gasket 535. The outer circumference of the sealing gasket 534 and the inner circumference side wall of the collecting tube 538 are slidably sealed, so that water entering the collecting tube 538 will not leak from between the sealing gasket 534 and the inner wall of the collecting tube 538 to the right side of the sealing gasket 534, and the setting of the sealing gasket 534 will not affect the rotation and left-right movement of the rotating shaft 532. Through the clamping effect of the shoulder 533 and the gasket 535 on the sealing gasket 534, it can be ensured that the outer circumference of the sealing gasket 534 can be evenly fitted with the inner circumference side wall of the collecting tube 538 during the left-right movement of the rotating shaft 532, so as to maintain good sealing performance.

[0117] The outer diameter of the sealing gasket 534 and the outer diameter of the rotating shaft 532, as well as the inner diameter of the collecting tube 538, are all interference-fitted to ensure sealing reliability. Preferably, a leather cup structure opening to the left can be provided on the outer left surface of the sealing gasket 534. When there is pressure on the left side or the sealing gasket 534 moves to the left, the opening of the leather cup structure is pressed against the inner diameter surface of the collecting tube 538, which can better strengthen the seal and prevent water leakage.

[0118] In a further solution of this embodiment, the filter portion 539 is disposed on the side wall and bottom wall of the collecting cylinder 538, and is spaced apart from both the left and right ends of the collecting cylinder 538. The setting range of the spiral piece 531 along the axis of the rotating shaft 532 at least extends from the area between the filter portion 539 and the left end of the collecting cylinder 538 to the area between the filter portion 539 and the right end of the collecting cylinder 538.

[0119] In the above scheme, the wastewater entering the collection barrel 538 flows to the area where the filter 539 is located, and the filter 539 intercepts impurities such as micro-thread scraps in the wastewater, and the wastewater without impurities can flow out through the filter 539, so that the micro-thread scraps accumulated in the collection barrel 538 are mainly concentrated on the filter 539. Since the filter 539 is located in the area close to the middle along the axial direction of the collection barrel 538, and there are spiral sheets 531 on both sides of the filter 539, the micro-thread scraps can be optionally transported to the right end for extrusion and dehydration, or transported to the left end and then sent to the storage unit 510 for storage by driving the rotating shaft 532 to rotate in different directions.

[0120] Specifically, the filtering accuracy of the filter part 539 is at least not lower than the filtering accuracy of the filter screen 493 in the wire scrap separation device 490, that is, the filtering aperture of the filter part 539 is not larger than the filtering aperture of the filter screen 493 in the wire scrap separation device 490. In this way, it can be ensured that the impurities such as micro wire scraps carried in the wastewater discharged by the wire scrap separation device 490 can be completely intercepted inside the collection tube 538.

[0121] As a specific solution, the number of filtering meshes of the filter part 539 is consistent with the number of filtering meshes of the filter screen 493.

[0122] Furthermore, a water collecting tank 563 is provided below the filter 539 to receive the filtered water discharged from the water outlet. The bottom of the water collecting tank 563 is connected to an internal drainage pipe 564, and the water entering the water collecting tank 563 can be discharged from the washing device along the internal drainage pipe 564.

[0123] As a preferred solution of this embodiment, the top of the spiral piece 531 has a certain width, and there is a certain angle between the top of the spiral piece 531 and the spiral surface of the spiral piece 531, forming a blade-like structure. In this way, when the spiral piece 531 rotates with the rotating shaft 532, the top of the spiral piece 531 passes through the upper side of the filter part 539, and can also cut off the wire scraps that have penetrated into the filter holes on the filter part 539, just like a razor cuts off beards through a mesh cover, thereby achieving self-cleaning of the filter part 539 and preventing the wire scraps from clogging the filter part 539.

[0124] It is understandable that some of the cut wire scraps located in or outside the filter holes may be washed into the sump 563 by the water flow, but the wire scraps that can be mixed into the water and discharged indicate that their diameter is smaller than the filter hole diameter on the filter part 539. Wire scraps of this size are allowed to be discharged by regulations.

[0125] As a preferred solution, the collecting tube 538 is made of stainless steel, which is wear-resistant and corrosion-resistant. A plurality of through holes that penetrate inside and outside are provided in a local area of ​​the bottom of the side wall of the collecting tube 538 as filtering holes, and the area where the plurality of filtering holes are concentrated is recorded as the filtering part 539. The collecting tube 538 made of stainless steel is also easy to process filtering holes thereon to form the filtering part 539.

[0126] In this embodiment, a water inlet 562 is provided on the side wall of the collection tube 538, and wastewater discharged along the wastewater return pipe 440 enters the collection tube 538 through the water inlet 562. Specifically, the water inlet 562 is provided in the upper area of ​​the side wall of the collection tube 538, and the downward projection of the water inlet 562 is staggered with the rotating shaft 532.

[0127] By staggering the water inlet 562 and the rotating shaft 532 in the vertical direction, it is possible to prevent the waste water entering through the water inlet 562 from falling directly onto the rotating shaft 532, thereby preventing the problem of wire scraps being contaminated by the rotating shaft 532 and being difficult to fall off.

[0128] Specifically, the water inlet 562 is connected to the water receiving pool 561 located outside the collecting tube 538, and the water receiving pool 561 extends upward from the water inlet 562, and can be a runway-type long tube structure. The upper side of the water receiving pool 561 is open, and the lower end of the wastewater return pipe 440 extends into the upper side of the water receiving pool 561, so that the wastewater discharged along the wastewater return pipe 440 is received by the water receiving pool 561, and the wastewater then flows into the collecting tube 538 through the water inlet 562. The water receiving pool 561 can temporarily store part of the water when the amount of wastewater mixed with high-concentration wire scraps is too much, so as to prevent the wastewater discharged along the wastewater return pipe 440 from overflowing.

[0129] Preferably, in this embodiment, the filter portion 539 covers a certain length along the axial direction of the collecting tube 538, and the water inlet 562 is located within the coverage of the filter portion 539 in the axial direction of the collecting tube 538. In this way, wastewater entering through the water inlet 562 is more easily filtered by the filter portion 539 below and then discharged.

[0130] In a preferred embodiment of the present invention, the axis of the collecting barrel 538 is tilted relative to the horizontal direction, and the left end of the collecting barrel 538 is higher than the right end. That is, the axis of the collecting barrel 538 can be installed at a certain angle to the horizontal direction, such as 15°. In this way, on the one hand, the water entering the collecting barrel 538 will not easily flood the puncture portion 5221, which can avoid re-wetting some of the micro-wire scraps that have been squeezed out and remain in the puncture portion 5221. On the other hand, when the rotating shaft 532 does not rotate, the water and micro-wire scraps in the collecting barrel 538 can also remain in the right end area of ​​the collecting barrel 538, which is convenient for squeezing out water.

[0131] The micro-lint collecting device 500 provided in this embodiment is applied to a washing device, and the collected micro-lint can be squeezed dry of most of the water and then compressed for storage, and the storage cylinder 511 for storing the micro-lint can remain sealed, effectively preventing the problem of micro-lint being easily moldy and producing odor. The micro-lint is compressed and then stored, which greatly reduces the storage space occupied by the micro-lint. By reasonably designing the volume of the storage cylinder 511, it can be achieved that the user does not need to manually clean it during the life cycle of the washing device, thereby improving the user experience.

[0132] Embodiment 2

[0133] like Figures 1 to 7 As shown, this embodiment is a further limitation of the above-mentioned embodiment 1, and a heating unit is provided on the outer side of the collecting cylinder 538 for heating the micro-wire scraps accumulated in the collecting cylinder 538, so as to completely dry the micro-wire scraps and then send them to the storage unit 510.

[0134] In a specific embodiment, since the micro-wire scraps are mostly attached to the bottom area of ​​the collecting tube 538, the heating unit is arranged below the collecting tube 538. At the same time, the collecting tube 538 is made of metal, preferably stainless steel, which has good thermal conductivity and can achieve uniform heating and drying of the internal micro-wire scraps.

[0135] As a specific solution of this embodiment, the heating part includes a first heating part 551, which is arranged in the area outside the collecting tube 538 close to the left end of the collecting tube 538. The first heating part 551 can be used to heat and dry the micro-wire scraps located in the left area of ​​the filtering part 539.

[0136] More specifically, the first heating part 551 extends from the left end of the collecting tube 538 to the left end close to the filtering part 539 along the axial direction of the collecting tube 538. On the one hand, the first heating part 551 can be used to heat the compression part 522, and dry the micro-wire scraps that remain inside the compression part 522 during the previous compression and transportation of the micro-wire scraps and are wetted by water again during the current collection and filtration process. On the other hand, the micro-wire scraps attached to the left side of the filtering part 539 on the side wall of the collecting tube 538 can also be dried.

[0137] Furthermore, a plurality of air holes 553 are provided in the upper area of ​​the side wall at the left end of the collecting tube 538. When the compression member 522 is pushed to the left to push open the sealing valve plate 513, the air holes 553 can provide an air pressure balance. At the same time, the downward projection of the air holes 553 falls on the compression neck 5222 of the compression member 522. When the first heating part 551 is working, heat can be dissipated outwards through the air holes 553 and water vapor can be discharged.

[0138] In this embodiment, the heating part may further include a second heating part 552, which is arranged in the area outside the collecting tube 538 close to the right end of the collecting tube 538. The second heating part 552 can be used to heat and dry the micro-wire scraps located in the area on the right side of the filtering part 539.

[0139] Specifically, the second heating portion 552 extends from the right end of the collecting tube 538 to the right end close to the filtering portion 539 along the axial direction of the collecting tube 538. The first heating portion 551 and the second heating portion 552 are separated by the water collecting tank 563, and the extension length of the first heating portion 551 in the axial direction of the collecting tube 538 is greater than the extension length of the second heating portion 552 in the axial direction of the collecting tube 538.

[0140] It is understandable that, in another specific embodiment, the micro-wire chip collecting device may also be provided with only one of the first heating part or the second heating part.

[0141] Furthermore, in this embodiment, the micro-yarn scraps collecting device 500 is provided with both the first heating unit 551 and the second heating unit 552. As a specific implementation, the micro-yarn scraps collecting device 500 performs the following control process.

[0142] After the control valve 480 opens and connects the wastewater return pipe 440, the wastewater is discharged into the water receiving pool 561 along the wastewater return pipe 440, and then enters the collecting barrel 538 through the water inlet 562. After the wastewater is filtered by the filter unit 539, impurities such as micro-thread scraps are intercepted on the inside of the collecting barrel 538. When the wastewater entering the collecting barrel 538 is completely filtered, the collecting motor 581 is started to drive the worm gear 571 to rotate in the second direction, thereby driving the rotating shaft 532 and the spiral sheet 531 to rotate in the second direction synchronously, and the micro-thread scraps in the collecting barrel 538 are gathered to the right end to squeeze out the water. During the extrusion process or after the extrusion is completed, the second heating unit 552 is started to concentrate on drying the micro-thread scraps at the right end of the collecting barrel 538, and the drying efficiency is higher.

[0143] After drying is completed, the collection motor 581 drives the worm gear 571 to rotate in the first direction, thereby driving the rotating shaft 532 and the spiral sheet 531 to rotate in the first direction, and at the same time, the rotating shaft 532 pushes the compression member 522 to the left, so that the puncture part 5221 pushes open the sealing valve sheet 513. In this process, the first heating part 551 is started, and the micro-line scraps are dried again during the compression process to ensure that the micro-line scraps entering the storage unit 510 are completely dried.

[0144] As another specific implementation, the micro-wire collecting device 500 executes the following control process.

[0145] When the wastewater entering the collection barrel 538 is completely filtered, the first heating unit 551 and the second heating unit 552 are started at the same time to heat and dry the micro-wire scraps evenly covering the bottom of the collection barrel 538. With this drying method, since the collection barrel 538 made of stainless steel has good thermal conductivity and the micro-wire scrap layer is very thin, it is also easy to dry the micro-wire scraps. When the wire scraps are completely dried, the collection motor 581 is started again to make the rotating shaft 532 and the spiral plate 531 rotate synchronously in the first direction, open the sealing valve plate 513 and transport the micro-wire scraps to the compression member 522 at the left end, and finally send them to the storage unit 510.

[0146] During the process of conveying the micro-thread scraps to the left, the second heating unit 552 is turned off, and the first heating unit 551 can be turned off at the same time, or it can continue to operate for a period of time to ensure that the micro-thread scraps sent to the storage unit 510 are completely dried.

[0147] Furthermore, in this embodiment, the heating part may adopt a PTC heating module or an electromagnetic heating module. When the PTC heating module is adopted, the PTC heating module is arranged at the bottom of the collecting tube 538, and semi-surrounds the collecting tube 538. When the electromagnetic heating module is adopted, the electromagnetic induction coil of the electromagnetic heating module is wound around the periphery of the collecting tube 538. The electromagnetic induction coil can generate an alternating current under the control of the driving module, thereby generating an alternating magnetic field. The alternating magnetic field induces eddy current in the collecting tube 538. The eddy current generates heat due to the resistance of the collecting tube 538, and the heating speed is faster.

[0148] In this embodiment, by setting a first heating part 551 and / or a second heating part 552 on the outside of the collecting tube 538, the collected micro-wire scraps can be dried first and then sent to the storage unit 510 for storage. The micro-wire scraps stored in the storage tube 511 are in a completely dry state, and are sealed and preserved in conjunction with the setting of the sealing valve plate 513. They no longer receive water vapor and can remain clean for a long time.

[0149] Embodiment 3

[0150] like Figures 1 to 7As shown, this embodiment is a further limitation of the above-mentioned embodiment one or two, and the outlet end of the inner drain pipe 564 extends into the outer drain pipe 461 of the washing equipment, and the drainage water flow in the outer drain pipe 461 can be used to pass through the outlet end of the inner drain pipe 564 to generate negative pressure, and then the accumulated water in the sump 563 can be pumped out along the inner drain pipe 564.

[0151] Specifically, the outer drain pipe 461 has a discharge section 4612 extending downward, and the inner drain pipe 564 is at least partially located inside the discharge section 4612 and extends in the same direction, and the extended end forms the outlet end of the inner drain pipe 564. The outlet end of the inner drain pipe 564 is lower than the height of its inlet end and has a certain distance from the end of the outer drain pipe 461.

[0152] With the above structure, when the three-way valve 470 conducts the clean water outlet pipe 460 and the outer drainage pipe 461, the water pump 420 starts to run and can drain water outward along the outer drainage pipe 461. At this time, the drainage water flows through the outer side of the inner drainage pipe 564, and the outlet end of the inner drainage pipe 564 is shorter than the end of the outer drainage pipe 461. Therefore, at the outlet end of the inner drainage pipe 564, according to the Bernoulli principle, the water flowing downward will form a certain negative pressure and generate suction force, so that the accumulated water in the water collection tank 563 is pumped out from the inner drainage pipe 564. When the inner drainage pipe 564 is filled with water, a siphon effect can also be formed. At this time, even if the water pump 420 stops working, so that there is no drainage water flowing through the outer drainage pipe 461, the inner drainage pipe 564 can still continue to pump water from the water collection tank 563 through the siphon effect until the accumulated water in the water collection tank 563 is completely drained.

[0153] In a further solution of this embodiment, the inner drainage pipe 564 at least includes a drainage front section 5641 and a drainage rear section 5642. The drainage front section 5641 is connected to the water collecting tank 563 and at least partially extends upward. The drainage rear section 5642 is connected to the portion of the drainage front section 5641 extending upward, and is located inside the discharge section 4612 of the outer drainage pipe 461 and extends in the same direction. The extended end of the drainage rear section 5642 forms the outlet end of the inner drainage pipe 564.

[0154] As a specific embodiment, the micro-lint collecting device 500 is arranged near the front side of the housing 100, and the discharge section 4612 of the external drainage pipe 461 is located at the rear side of the housing 100. The drainage front section 5641 of the internal drainage pipe 564 first extends backward to the area near the rear side of the housing 100 below the water storage cylinder 200, and then extends upward.

[0155] Preferably, in order to completely drain the accumulated water in the water collection tank 563, the inlet end of the inner drainage pipe 564, that is, the front end of the drainage front section 5641, is arranged close to or in contact with the bottom of the water collection tank 563. More preferably, the inlet end of the inner drainage pipe 564 is arranged flush with the bottom wall of the water collection tank 563, so that the accumulated water in the water collection tank 563 can be pumped out as thoroughly as possible.

[0156] In this embodiment, the cross-sectional area of ​​the inner drain pipe 564 is smaller than the cross-sectional area of ​​the outer drain pipe 461, so that inside the discharge section 4612 of the outer drain pipe 461, there is a gap between the outer wall of the inner drain pipe 564 and the inner wall of the outer drain pipe 461. In this way, the washing equipment is ensured to drain smoothly along the outer drain pipe 461.

[0157] In a further solution of this embodiment, the outer drainage pipe 461 further includes a water guide section 4611 disposed upstream of the discharge section 4612, and the water guide section 4611 and the discharge section 4612 are connected via an adapter 700 disposed therebetween. The drainage front section 5641 of the inner drainage pipe 564 is located outside the outer drainage pipe 461, and the drainage front section 5641 and the drainage rear section 5642 are connected at the location where the adapter 700 is disposed.

[0158] Specifically, the water guide section 4611 is located above the water storage cylinder 200 , and the water guide section 4611 is connected to the top of the discharge section 4612 . The adapter 700 is located at the top of the discharge section 4612 , and is preferably arranged on the inner side of the housing 100 .

[0159] In this embodiment, the inner drain pipe 564 extends from the middle section of the outer drain pipe 461 into the outer drain pipe 461, and good sealing performance needs to be ensured at the position where the inner drain pipe 564 extends into the outer drain pipe 461. By providing a separate adapter 700 for installing the inner drain pipe 564, it is only necessary to connect the water guide section 4611 and the discharge section 4612 of the outer drain pipe 461, and the drainage front section 5641 and the drainage rear section 5642 of the inner drain pipe 564 to the reserved interfaces on the adapter 700, which greatly simplifies the assembly process.

[0160] In this embodiment, the lower end of the purified water outlet pipe 460 is connected to the three-way valve 470 located above the water storage cylinder 200. The inner circulation pipe 462 extends downward from the three-way valve 470 and is connected to the wall of the water storage cylinder 200, or the outlet end of the inner circulation pipe is connected to the observation window pad at the mouth of the water storage cylinder, and water returns to the water storage cylinder through the observation window pad. The water guide section 4611 of the external drainage pipe 461 extends backward from the three-way valve 470 and is connected to the adapter 700. The adapter 700 is further connected to the discharge section 4612. The discharge section 4612 extends to the outside of the housing 100 and extends downward, and can be inserted into the floor drain to achieve drainage.

[0161] One end of the wastewater return pipe 440 is connected to the wastewater outlet 4923 of the wire scrap separation device 490, and is at least partially extended downward. The lower end of the downwardly extended part extends into the water receiving pool 561 of the micro-wire scrap collection device 500, so that the wastewater carrying wire scraps can flow along the wastewater return pipe 440 to the micro-wire scrap collection device 500 under the action of gravity.

[0162] A filter 539 is provided at the bottom of the collection barrel 538 of the micro-line dust collection device 500, and a water collection tank 563 is provided below. The waste water entering the collection barrel 538 is filtered by the filter 539 and then discharged into the water collection tank 563. The front end of the drainage front section 5641 of the inner drainage pipe 564 is connected to the water collection tank 563, and the upper end is connected to the adapter 700. The drainage rear section 5642 is located inside the discharge section 4612 of the outer drainage pipe 461, and the upper end is connected to the adapter 700, and the lower end extends to a position lower than the lower end of the drainage front section 5641 and higher than the end of the outer drainage pipe 461. In this way, when the washing device performs the drainage action, the drainage water flow is discharged along the outer drainage pipe 461, and then a negative pressure can be formed at the outlet end of the inner drainage pipe 564, the water in the water collection tank 563 is pumped out and a siphon effect is formed, and finally, under the siphon effect, the accumulated water in the water collection tank 563 can be completely discharged.

[0163] Embodiment 4

[0164] like Figures 1 to 9 As shown, this embodiment is a further limitation of the above-mentioned embodiment three, and the adapter 700 includes an outer shell 710 and an inner tube 720, wherein the outer shell 710 is used to connect the water guide section 4611 and the discharge section 4612 of the external drainage pipe 461, and the inner tube 720 is used to connect the front drainage section 5641 and the rear drainage section 5642 of the internal drainage pipe 564.

[0165] Specifically, the outer shell 710 is a tubular structure with a certain extension length, with a first opening 711 at the right end thereof for connecting to the water guide section 4611 of the outer drain pipe 461, and a second opening 712 at the left end thereof for connecting to the discharge section 4612 of the outer drain pipe 461. The main body of the inner tube 720 is installed inside the outer shell 710, and the first end 721 of the inner tube 720 is used to connect to the drainage front section 5641 of the inner drain pipe 564, which passes through the side wall of the outer shell 710 and extends to the outside of the outer shell 710, and is sealed with the side wall of the outer shell 710. The second end 722 of the inner tube 720 is used to connect to the drainage rear section 5642 of the inner drain pipe 564, which extends from the second opening 712 of the outer shell 710.

[0166] When the adapter 700 having the above structure is used to assemble the internal pipelines of the washing device, the end of the water guide section 4611 of the external drainage pipe 461 is sleeved on the right end of the outer shell 710 and communicated with the first opening 711, and the top of the discharge section 4612 is sleeved on the left end of the outer shell 710 and communicated with the second opening 712. The top of the drainage front section 5641 of the internal drainage pipe 564 is sleeved on the first end 721 of the inner tube 720, and the top of the drainage rear section 5642 is sleeved on the second end 722 of the inner tube 720. Both the internal drainage pipe 564 and the external drainage pipe 461 can be made of elastic material to ensure the sealing of the sleeve.

[0167] Preferably, at least one circle of ribs 714 are respectively provided in the areas near the two ends of the side wall of the outer shell 710 , so as to further enhance the connection sealing between the outer shell 710 and the water guide section 4611 and the discharge section 4612 .

[0168] In a further solution of this embodiment, the inner tube 720 has a non-return structure 726 that conducts unidirectionally from the first end 721 to the second end 722. The non-return structure 726 can be used to control the water in the inner drainage pipe 564 to flow out in one direction. In this way, when the outlet of the discharge section 4612 is accidentally blocked, the non-return structure 726 can prevent the water in the inner drainage pipe 564 from flowing back into the water collection tank 563.

[0169] As a specific embodiment, the inner tube 720 includes a first connecting tube 723 and a second connecting tube 724 that are sleeved and connected. The first connecting tube 723 is a curved tube, the lower end of which passes through the side wall of the outer shell 710, and the upper end is bent to the left and parallel to the central axis of the outer shell 710. The second connecting tube 724 is sleeved on the upper end of the first connecting tube 723 and extends out of the second opening 712 of the outer shell 710, and the non-return structure 726 is disposed in the second connecting tube 724. Preferably, the second connecting tube 724 is coaxially disposed with the outer shell 710.

[0170] Furthermore, in this embodiment, a fixing portion 725 protruding outward is provided on the outer peripheral wall of the inner tube 720 in a region close to the first end 721 , and the fixing portion 725 is connected to the mounting portion 713 on the side wall of the outer shell 710 for fixing the inner tube 720 .

[0171] As a specific implementation, the inner tube 720 is provided on the side wall of the outer shell 710 in a direction perpendicular to the central axis of the outer shell 710, and the fixing portion 725 is a plate-like structure perpendicular to the axis of the inner tube 720, preferably arranged around the inner tube 720. The mounting portion 713 protrudes from the side wall of the outer shell 710, and the fixing portion 725 is connected and fixed to the protruding top surface of the mounting portion 713 by screws 740, so that the inner tube 720 and the outer shell 710 are relatively fixed, ensuring that the second connecting tube 724 is coaxially arranged with the outer shell 710.

[0172] Furthermore, a mounting opening is provided in the middle of the raised mounting portion 713, which is connected to both the inner and outer sides of the housing 710, and the first end 721 of the inner tube 720 extends from the mounting opening to the outside of the housing 710. A sealing member 730 is provided between the inner wall of the mounting opening and the outer peripheral wall of the inner tube 720, thereby ensuring that there is no water leakage at the mounting opening.

[0173] As a preferred solution, the inner wall of the installation opening is a stepped structure, and the inner diameter of the installation opening near the inside of the housing 710 is smaller than the diameter of the installation opening near the outside of the housing 710. The seal 730 is sealed on the inner tube 720, and the outer peripheral wall of the seal 730 is a stepped structure matching the inner wall of the installation opening. The seal 730 is installed in the installation opening to achieve sealing.

[0174] In another specific solution of this embodiment, the adapter may also adopt an integrated structure, that is, the outer shell and the inner tube are connected in one piece, which can save the assembly process of the adapter.

[0175] This embodiment provides a specific structure of an adapter 700 to facilitate the assembly of the external drainage pipe 461 and the internal drainage pipe 564 .

[0176] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
